A DUAL POLARIZATION ANTENNA USING INVERTED-F ANTENNA

摘要

The present invention relates to a dual polarized antenna using an inverted F antenna, comprising: a ground plate, a first and second inverted F antennas installed in a phase opposite to one side of the ground plate, and the first and second station It is installed so as to face each other to be perpendicular to the F antenna, it characterized in that it comprises a third and fourth inverted F antenna to be fed so that the phase difference 180 °.;According to the present invention as described above, by using two pairs of inverted F antenna is excellent in the orthogonality, and the polarization characteristics are duplicated into vertical polarization and horizontal polarization to reduce the radio shade area to extend the transmission distance between the reader and the tag and within the service interval It is effective to improve the communication quality at.;Antenna, reverse antenna, dual polarization, RFID,
